Two decorative chomo-lithographs from 1898 depicting 28 kinds of floating algae and plankton.
Each lithograph has a semi-transparent equivalent outlining the objects and naming them.
Each lithograph (2 singles) measures 6 ½ x 9 ½ inches (16 x 24 cm).
They look great when matted and framed and make unique gifts.
